[PATCH kvmtool 0/9] Disk fixes and AIO reset

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Patches 1-7 fix a few issues found while testing disk backends, and
patches 8-9 implement reset for the AIO backend. By draining the AIO
queue on reset, we avoid writing I/O completions to the used ring after
the guest reclaimed the ring's pages.

Jean-Philippe Brucker (9):
  qcow: Fix qcow1 exit fault
  virtio/blk: Set VIRTIO_BLK_F_RO when the disk is read-only
  guest: sync disk before shutting down
  disk/aio: Refactor AIO code
  disk/aio: Fix use of disk->async
  disk/aio: Fix AIO thread
  disk/aio: Cancel AIO thread on cleanup
  disk/aio: Add wait() disk operation
  virtio/blk: sync I/O on reset
